Application area and features

• Universal KNX actuator with 8 freely configurable output channels for switch, shutter (AC/DC), fan coil, or valve control.
• KNX Secure capable, configured via ETS5 or higher.
• Switch outputs: time functions (on/off delay, flashing, staircase lighting), 8 scenes, logic (AND, OR, XOR, GATE), status response, forced operation, operation-hours counter.
• Heating actuator mode: switch outputs drive thermal heating valves directly (PWM or 2-point), without a separate controller.
• Shutter AC/DC outputs: up/down, position 0-100%, louvre adjustment, 8 scenes, automatic sun protection, safety function, two modes (Venetian Blind / Shutter).
• Fan coil outputs: up to 3-level fan speed, step-switch and steering-switch modes, automatic, manual and forced operation.
• Valve outputs: continuous (3-point), PWM and 2-point switching; valve-curve correction and automatic cleaning for continuous valves.
• Manual operation buttons on the device for commissioning and diagnostics.
• Configurable behavior on bus voltage failure and recovery.
• Powered directly via the KNX bus, no additional supply voltage required.
